Fig. 20 is an enlarged sectional detail taken on the dotted line 20-20 of Fig. 16; and Fig. 21 is a sectional detail taken on the dotted line 21-21 of Fig. 20 looking toward the right.

Referring to Figs. 1, 4 and 12 of the drawings the machine shown herein embodying my invention comprises a hopper 1 for receiving dough or other plastic material, the base 2 of said hopper bein bolted upon suitable front and rear side rames 3. t

The dough may be fed through the hopper by feed rolls 4 having journals 5 remov ably mounted in 6 1. 2) in arms 7, said bearings aving cape 8' hinged thereto, which may 1v v w when closed by suitably swing-locking bolts 10. Said dough feed rolls may be moved toward and from each other to go the amount of material fed therethrougi and may be separated to facilitate their removal from their hearings in a suitable manner. Herein the said arms 7 are made fast at their lower ends to shafts 12 journaled in continuous bearings 13, whereby said arms and their rolls may be swun toward and from each other as desired. aid arms 7 may be accurately adjusted about their fulcrums by any suitable means. Herein the roll carrying arms at their upper free ends carry the transverse shafts 15 having fast thereon eccentrics 16, the stra s of which are formed in the ends of theinks or arms 17, which are pivotally connected to the outside of the hopper ends and said shafts are provided with handles 18 whereby they may be turned and through their eccentrics cause said roll carryin arms and the rolls therein to be adjusts toward and ifrom each other. To permit a complete separation of said feed roll arms for the purpose of removing said feed rolls, I have herein made the bearings for the eccentric shafts 15 separable, as shown in Fig. 2, wherein they are indicated as provided with hinged caps 21 adapted to be ocked in position by swin bolts 22.

The dough feed rolls are riven. by spur gears 25 igs. 4 and 16) fast to the rear ends of the roll shafts 5, said gears being driven b intermeshing spur gears 26. loosel moun on the projec ends of the fa crum shafts 12 for said rol su porting arms. Since the latter swing about t e axes of said shafts 12 the roll gears 25 will always be in mesh with the gears 26, whatever the adjusted positions of said feed rolls. One of said gears 26 is made fast to a large gear 27, mounted on the same shaft therewith. This gear 27 is driven b a pinion 28 loosely mounted on a stud sha 30 Fig. 16) more fully hereinafter described. eyed upon the hub of the pinion 28 is a large spur gear 31 meshing with and driven by a pinion 32 fast to a shaft 33, mounted in hearings in the side frames 3 and driven lg any suitable variable speed mechanism. erein I have shown as an example of a mechanism the well known Reeves variable transmission, herein illustrated as comprising the said shaft 33, the adjustable cone disks 34 thereon, the adjacent and parallel shaft 35 journaled in the side frames 3 (see Fig. 4), the similar cone disks thereon and the connecting belt or flexible transmission member 37. This last mentioned shaft 35 constitutes herein the main or driving shaft for the machine, and is therefore provided with fast and loose pulleys 38 and 39 by which to drive the same. Referring to Fig. 1, I have shown near the lower left hand front of the machine an adjustable hand wheel 10, by which to adjust said Reeves mechanism to permit said dough feed rolls to be driven through the mechanism described at any desired rotative speed, for the purpose of delivering the dough sheet or bars at any desired rate of speed.

Referring to Fig. 12, the dough feed rolls 4 are rotated by the mechanism described in opposite directions to frietionally engage the dough in the hopper and feed it downwardly between them, the amount of material fed being regulated by moving said rolls toward and from each other as de scribed. The dough thus fed or nipped between said rolls is crowded down into the lower portion of the hopper and is pri vented from adhering to said rolls by scraper blades 42, Fig. 12, the lower edges of which rest in longitudinal grooves in the roller arm fulcrum shafts l2 referred to, the bearings 13 near said blades being cut away for the purpose. These scrapers are inclined inwardly presenting sharp edges contiguous to said feed rolls. and are held in position by back supports 4-1, parallel to said blades and fixed to said roll arms whereby the roll carrying arms, the rolls and scraper blades move as a unit during adjustment. The dough forced down into the chamber formed between said scraper blades is then passed through a die 45 '(Figs. 12, 13 and 20). This die is mounted in a die base 46 removably attached in said hopper base 2.

Heretofore so far as I am aware machines of this type have been provided with a plurality of dies, one to replace another when sheets of dough of different thickness are desired. Herein sheets of varying thickness may be formed by the use of a single die (see Figs. 12 and 13) comprising two adjustable cylinder die members 47 slabbed ofi' longitudinally at their adjacent sides to present opposite flat faces 49. The die members are journaled in bearings 50 and segmental seats 50 (see Fig. 20) in said die base 46, and may be turned to vary the opening between them by intermeshing pinions 51, and one of these pinions is made wider than the other for engagement with an actuating pinion'52 on a sleeve 53 of an adjustable hand wheel 54 loosely mounted on a supporting stud 55 carried by one of said side frames. Said pinion 52 with its sleeve and hand wheel are made to slide axially on their supporting stud 55 so that after the said die members have been assembled for adjustment, the same pinion 52 by which the adjustment was effected may be pushed inward to intermesh with the narrow pinion 51 which retains its engagement with the wider and inter-meshing pinion, thereby locking all three piuions against rotation and maintaining the adjustment of the die members against any possibility of change.

It will be apparent that the largest die opening will be obtained when the flat faces of said cylinders are in parallel vertical planes, as shown in Fig. 13. If the die members are turned to converge said faces downwardly toward each other, the lower edges thereof will approach, presenting a die opening which is wedge shaped in section, the narrowest opening occurring when said members are turned sufficiently to cause said flat faces to lie in the same horizontal plane. The described construction presents an adjustable die capable of adjustment, even while the machine is in motion to vary the thickness of sheet, produced to any desired degree, and without interruption of the oporation of the machine, and presents at all times and in any position of adjustment continuous smooth surfaces which insure best condition and delivery of dough. By desired assembling of the die rolls, the. angle at which. the dough issues from the die may be changed at will. The described die may also be readily opened or enlarged to free it of any foreign substance that may have found lodgment therein or for any other purpose desired.

With the die shown the dough or other plastic material issues therefrom in the form of a sheet, and is fed on to a continuous traveling apron 60 (see Fig. 12), mounted on a tilted carrier frame 61. This frame comprises front and rear angle bar mem bers or guides 62, provided with depending brackets 63, one of which, namely that at the right of Fig. 16, is pivoted on the inwardly projected end of the above referred to stud 30, the other said bracket being pivoted on a sleeve 65, on the opposite side of said frame. Mounted to slide on the guide bars 62 (see Fig; 12) are the transverse apron board supports, 66, which in turn support the apron board 67, comprising transverse members carried by and between the longitudinal angle bars 68 shown best in Fig. 16: The apron 30 hereinbefore referred to is mounted to travel over and upon said apron board (see Fig. 12), and at the left hand end of said board passes about a roller 70, returning along the under side of said apron board to a return roller 72 journaled in hearings on and movable with the right hand transverse supporting her 66 pendently operable adjusting devices, 76.' If one edge] portion of the apronshouldtravel more tightly .than the other, this irregularity may be com for by independently adjusting elther one of the said adyusting devices 76, or by independently.

ad]usting the arms 78 (see Figs. 14 and 15) supporting the roller 70 at the opposite end of the apron board.

The apron drive drum 73 may be driven any suitable variable speed mechanism. e

rem said drum is mounted fast on a drum 1 shaft 80- (see Fig. 16') one end of which is journaled in a recessed bearing in the inner end of the stud shaft 80 referred to. The opposite end of said shaft being extended through the sleeve about which one of said a ron frame brackets is pivoted as describe The stud 30 (Figs. 16 and 19) constitutes not only a bearing for -one end of said apron drum shaft, but also a bearing for the pinion 28, and one of said apron board pivot brackets. An intermediate portion of this stud 'is conical in form, and is not threaded directly into the corresponding'cone bore in the boss 30 'in the frame,

but herein said boss is bored larger than said cone, the latter being babbitted into said boss bore, furnishing a strong construction, easy to make and assemble, without the necessity of threading said cone bore.

Referring again to the apron drum shaft 80, the latter projects outwardly toward the front of the machine (see Figs. 1 and 17) and is driven by a Worm wheel 83, which meshes with a worm 84 fast to the upper end of the inclined worm shaft 85, which is located outside the frame in suitable bearings therein. A friction cone 86 is mounted fast to the lower end of said inclined shaft, and is ada ted to receive a variety of speeds from a iction wheel 87 (see Fig. 1) engagii ig and adjustable along the face thereof. his friction drive wheel is splined to an inclined shaft 88 journaled in bearings also upon the outside of the frame. This friction wheel shaft is driven by a bevel gear 89 fast to the upper end of its shaft, in turn driven by a bevel ear 90 fast on the main shaft 35 hereto ore re-.

ferred to. Said friction Wheel 87- may be moved along the face of said driven friction disk 86 to vary the speed transmitted to the latter by a fork 91 engaging a pcripheral groove 92 on the hub of said friction wheel, said fork being adjusted by a screw shaft 93 adjacent and parallel to said friction Wheel shaft 88, and controlled by a suitable hand wheel 94. Referring to Figs. 16 and 17, the worm gear referred to for driving the {gag-pndrum shaft 8Q may be connected ,di tosaid shaft for driving said drum at one speed or indirectly throu h a, train of is for driving it at a di erent speed. shown in said figures, said Worm .gear may be directly connected to said apron drum shaft by a double key 100 mounted to slide axially. in the end of said drum shaft 80, .and adapted when in its extreme outermost position to enter keyways 101 in the hub of said worm wheel, thereby to cause said worm wheel and shaft when connected to rotate as one. When said key is pushed inward to its extreme innermost position, it enters, keyways 102 in the hub of a spur gear 103, loosely mounted on said drum shaft. This gear meshes with and drives a spur gear 104 directly above it, and loosely mounted on a stud 105 on said frame. Fast upon the hub of the gear 104 is a second gear 106, which drives back into a smaller gear 107, fast upon, the hub of said worm wheel 83'. When driven through these gears the apron drum 73 will turn at a lower speed than when driven directly from said worm gear 83. When the key 100 is in mid position both the gear 103 and the worm wheel 83 are disconnected from the drum shaft, in which case the latter remains at rest, said key then standing stationarily in the counter bored hub of said I worm wheel, which turns idly about it. Thus is provided means for driving the dough carrier or apron 60 at a wide range of speed, and with all the fineness of gradation of speed made possible by the friction drive at the bottom of the worm shaft 85.

The sheet or series of bars being delivered upon the carrier are carried forward by, the latter, and delivered to a cuttingor other machine next to itor for any othertpurpose desired. Since the receiving ends of such other machine or machines may vary considerably in height from the floor, it is desirable to vary the height of the delivery end of the carrier, and I have herein provided for this by the tilting carrying frame 61. To this end the apron board angle boards are provided with supports 110 (see Fig. 12) pivoted at their outer and upper ends to said angle bars 68, and slotted at their lower ends to receive a clamping device hereinafter described. It is obvious that by slackening these clamping bolts the slotted supports 110 may be'adjusted to tip the carrier frame and its board and the apron tive' to any companion or other machine. To accomplish this, the transverse. board supports 66 on-the sidev members of the swinging frame 61' may he slid along the board supporting angle barsby means of depending racks 112; Figsrl and 12, which, together with theapron board 67, maybe moved forward or backward by the pinions 113 fast to a shaft 114, journaled in bearings in the front ends of said guide bars 62 of the apron board frame. said shaft being rotated by a suitable hand wheel 115 (see Fig. 1) at one end thereof. The apron board and its frame 62 are provided with additional supports 115 (see Fig. 12) depending from said pinion shaft 114. said supports being held in their adjusted positionsby the same clamping device which locks said arms 110. This locking device (see Figs. 3 and 12) comprises a clamping rod 116 mounted in said frames 3, said ro'd parsing through the slots in the supports and referred to. Said supports are separated by washers [17. the inner washers contacting with the opposite ends of a long sleeve 118 on said rod 116. A hand wheel 118 is threaded upon the end of said rod. the opposite end of the latter receiving a nut 119 engaging the outer face of one of the frames 3. Between the hand wheel and the innermost washer is a short sleeve 120. so that when the hand wheel is turned the sleeves and intervening washers are brought tightly to gether to clamp all of the said supports 110 and 115 simultaneously. constituting a simple and efficient clamping device permitting of ready adjustment of the carrier.

Referring more particularly to Figs 4, 5, 6 and 7, Hour boxes 121 may be attached on each side of 'said hopper to the dough feed roll arms 7 by arms-122 hooked over studs 123 on said roll arms. said boxes having suitable sieves, adapted to sift flour upon the sheet of dough fed beneath the same. These flour boxes may be vibrated or agitated in any suitable manner, as, for instance. by the mechanism shown in connection with one of Said boxes at the left of the hopper in Fig. 4. The rear end of said box is provided with a bracket 126 (see Fig. adapted to be struck intermittently by a hammer 127, the handle, 128, of which is fulcrumed between its ends on a pin 129 (see Fig. 7) in a forked head 130. This head 130 is fast upon the end of a rod 131, which is mounted to slide in said frames 3 and restrained from rotative movement thereon. but may be moved longitudinally by the hand wheel 132 (see Figs. 1 and 7) threaded upon one end of said rod for the purpose of adjusting the position of the hammer fulcrum at any time. Said hammer is provided with a follower 132 (see Fig. 5) pressed by a spring 133 on the end of said hammer into engagement with an annular cam groove 134, (see Fig. 6) on the face of a spur gear 135 rotative on a stud 136 fixed. inone of said frames 3: Said groove is provided with a ratchet tooth bottom whereby said hammer has imparted to it a rapid succession of hammer blows. The cam faced gear 135 mesheswith a pinion 137 one stud 138 on said frame, a sheave 139 being fixed to said pinionto rotate therewith. Said sheave is driven by a round belt 140 (see Figs. 4 and 8) from a sheave 141 fast to the main drive shaft 35.

A suitablersurface may be given the sheet of material fed by the carrier by a polishing plate (see Figs. 4, 8,9, 10 and 11) which may be of any suitable form, but is herein shown as U-shaped in section to prevent any roughening or mutilation of the sheet acted upon. In conjunction with this plate one or more surfacing or flour distributing brushes 151 may be used. Herein a brush is shown on each side of said plate, said 'brushes and plate being all carried by a back or support The plate and brushes are supported entirely by the sheet of material fed, but the brushes being lighter than said plate may be mounted to rest on said sheet inde pendently of said plate, said brushes being carried in suitable guides 153 in said support for this purpose. This support, 152, may be given an oscillatory or gyratory movement in a horizontal plane by crank pins 154, engaging slots 155 on the back of said support. Said pins depend from disks 156 (see Fig. 9) on the lower ends of vertical shafts 157. journaled in arms 158, extending laterally from front and rear brackets 159. These brackets are pivoted on the outside. of the apron board angle bars 68, said brackets hein supported in place when tipped down into position by a transverse bar 160 (see Fig. 1) connected to said angle bars. and may be held in position by locking bolts 161. The brackets may be tipped backward on their pivots to raise said polishing devices when desired as when starting a new or broken sheet and by loosening said locking bolts said polishing devices may be removed. The brush and late aetuating shafts 157 may bedriven by beveled gears 163 fast to the upper ends thereof. said gears meshing with beveled gears 164 fast on the shaft 165 journaled in hearings in the upper ends of said brackets. The shaft 165 projects outwardly to receive a sheave 166, (see Figs. 4 and 8) which may be driven from a sheave 167 fast to said hammer pinion 137. on the stud 138, (see Fig. 5). said sheaves 166. and 167 being connected by a round belt. 168 guided over idler sheaves 169 on the pivot pin of one of said brackets.

When two different doughs are used for layer. filled or stripe work and the like a division plate 170 (see Figs. 12 and 16) mar be introduced into said hopper between said iced rolls. Said plate when inserted is ded mfical grooves 171 in the inte rim of the ends of said hopper and rests upon the ends of said die base 46.

In the use of the machine described the dough as lied the hopggr 1, a large or amount of d h' mg fed thereaecording to t e relative positions of the dough iced rollsi, and their speed of rotation which may be adjusted by the Reeves variable speed transmission. These rolls are continuously driven and may be swung into position of adjustment without afie their drive. The dough is mpped by said rolls 4 as they rotate toward each other and is. fed down into the chamber beneath the same, the dough being then forced throw die 45 in a. homogeneous sheet. The of this sheet may be regulated g the flat faced die cylinders .47 by the hand wheel 57 until the die opening is obtained, said wheel being then pushed in to cause the die adjusting fusion 52 to mesh with both of said efylin r pinions 51, thereby securely lor'lcinfisglhe same in their adjusted positions as L ibed. It will be ap arent that by adjusting said dough feed ro s and said die, ofanaterial of great variety of consistency form may be died out without the removal or replacement of any parts. If layer work is desired the diVlsion plate 110 is inserted between the feed roll-s 4 and two different doughs may then be fed to said die. This machine nlay not only be used to produce sheet work, but also bar work may be readily produced by simply remwing said sheeting die and-insert ing a bar of usual construction not shown here. Thedough thus shaped by said adjustable die 45 is fed on to the continuously traveling apron 60, and the dough sheet fed along thereby may be delivered to any suitable cutting machine for cutting out cakes imam said sheet as desired. To this end the am carriage 61 may be tilted to the planner inclination to conform to the cutting machine and may be adjusted longitudinally fiurflaer to properly position said apron respect to aid machine. When frofperly whim the apron carriage-may be ocked in place its clamping device.

The die may be adjusted also to supply a stat of greater or less thickness to the angle to which the carrier.

is If @e carrier were inclined dewmwamdly toward its delivery end the direction of travel of the dough sheet issuing from he die would be changed from a right to an awe. whereas if tilted up its be changed to an acute angle, and if we dough sheet were thick this sharp acme head by compressing the top sin-face md stretching the lower surface of the sheet would destroy more or the smooth surface imparted by said die, an

action, however, which would be less effective on thinner sheets.

Tlie two speeds transmitted to the feed apron drum by the direct and indirect connection of the worm wheel 83 to the apron drumshaft 80 may be varied to give a wide range of speed with a nicety of speed gradation by adjusting the drive friction wheel along the face of the driven friction disk.

The dough sheet passes under the" flour box 121, thelatter being 'ven the desired degree of blow by the a justable hammer 127 to shake a large or small amount of flour on the sheet passing therebeneath. The dou h sheet then passes beneath the surfacing rushes and plate, which are supported on said sheet and receive a gyratory or oscillatory movement simultaneously.

By my invention all of the rincipal adjustments may be made while I; e machine is in motion, the machine being simple in construction, readily accessible and easy to 0perate. By my invention alsoa machine 1s provided having a capacity for producing a great variety of product with few and simple adjustments.

It w1ll be understood that m invention is applicable to machines of the c as for treating plastic material and is not limited to the artlcular embodiment shown herein, but hat various modifications ma be made without departing from the spirlt of my invention.
